```suggestion
Sending a CONNECTION_CLOSE of type 0x1d in an Initial packet might reveal application
state to third parties. To avoid this leakage, a CONNECTION_CLOSE of type 0x1d MUST
be replaced by a CONNECTION_CLOSE of type 0x1c when sending the frame in Initial
packets. Endpoints MUST clear the value of the Reason Phrase field and SHOULD use
the APPLICATION_ERROR code when converting to a CONNECTION_CLOSE of type 0x1c.
```
